[CSCI2194] ethics presentations

[Berna Massingill]

I've put details about the ethics presentations on the Web, linked
from the course Web page in a couple of places ("Useful links" and
also "Lecture topics and assignments").  I think all the details
are complete and correct, with the possible exception being the
information about the Center for Learning and Technology (formerly
IMS, and I hope a source of technical expertise about making videos,
and I've contacted them but have not received a reply).

I'll be sending specific problem scenarios to group leaders later
today or tomorrow.
